Murray putting US Open fitness concerns behind him

Andy Murray believes normal service has been resumed after he easily overcame Matthias Bachinger in straight sets to reach the third round of the US Open.

Murray endured a difficult first round win over Robin Haase earlier this week as the effects of cramp meant a laboured victory over the Dutchman.

The Scot had vowed to get to the bottom of the issue and his showing to dispatch world 235 Bachinger in the Arthur Ashe Stadium night match appeared to suggest that had been the case.

The biggest challenge facing Murray was the gusting breeze but he soon overcame the conditions to win 6-3, 6-3, 6-4.

It sets up a third round tie with Russia's Andrey Kuznetsov, who knocked out 31st seed Fernando Verdasco in five sets, and 2012 US Open champion Murray was content with his improvements from his previous match.

“It was extremely windy," said Murray. "That was the hardest part about the conditions; just very, very breezy and difficult to play close to the lines.

"But I hit the ball well considering, served better, and obviously I moved a bit better, as well.

"I hope I feel better every day now. I felt fine the last couple days and had no problems on the Tuesday or Wednesday. I practised well and didn't have any problem.”
